Can discounts save growth and hurt profit?

The Lululemon story turns a tempting sale sticker into a practical test of incremental demand, inventory and contribution.

The Useful Idea

Judge a promotion by additional contribution and later customer behaviour, while keeping inventory cash recovery separate from total profitability.

The sale sticker tells only half the story

A discount can attract a customer, clear an awkward size and bring cash into a business. It can also give away profit on something that would have sold at full price. That is the dilemma behind Lululemon’s pricing story: a busier store is encouraging, but activity and economic improvement are not the same measurement.

The useful question is not whether discounts are always good or always damaging. Ask what the promotion changes compared with a credible alternative. Does it create additional demand, move a future purchase into today or simply reduce the price paid by an existing customer? Those outcomes can produce similar-looking order counts while leaving very different amounts available to cover the business’s costs.

Twenty percent off can cost more than twenty percent of profit

Use a clearly hypothetical product priced at US$100 with US$40 of inventory cost. It generates US$60 of gross profit before other costs. A 20% discount reduces the price to US$80, while inventory cost remains US$40. Gross profit falls to US$40: a one-third reduction. These are teaching numbers, not the actual cost or margin of Lululemon leggings.

To restore revenue, the retailer needs 25% more units. To restore gross profit, it needs 50% more. Add an assumed US$5 of variable selling and fulfilment cost per unit, and contribution falls from US$55 to US$35. Restoring that contribution requires roughly 57% more units. Packing more parcels may be a necessary part of the plan. It is not evidence that the plan has paid for itself.

An improving reported margin can need a footnote

Lululemon’s reported gross margin in the quarter rose from 58.5% to 60.5%, while gross-profit dollars declined slightly. The quarter included US$134.5 million of tariff refunds reducing cost of goods sold. That benefit is different from persuading a customer to pay full price. Interest associated with the refunds was recorded outside gross profit and should not be folded into the same calculation.

Removing only the disclosed refund from gross profit and dividing by unchanged revenue gives approximately 54.95%. That is an explanatory calculation, not Lululemon’s adjusted margin and not an estimate of normal earnings. Other influences remain. The company’s bridge also does not isolate a precise markdown-only loss. The right response to a flattering percentage is to understand its ingredients before declaring either a recovery or a failure.

Inventory can release cash while recording a loss

Imagine an item already bought for US$40 that can now sell for US$35. The sale records a US$5 gross loss before other expenses, but it also brings in cash. That does not make the original purchase profitable. It separates the past cash cost from the decision now facing the business. Waiting, storage, further deterioration and the chance of a better later sale belong in the comparison.

Inventory quality matters as much as the total. A retailer can reduce units and still carry too many unwanted colours while running out of popular sizes. Lululemon’s reported inventory value and units did not move by the same percentage, so one cannot infer a universal price change from that difference. A useful internal view follows age, availability and full-price sell-through alongside the amount invested in stock.

Measure the customer after the promotion ends

Premium competitors such as Alo and Vuori give shoppers alternatives in product positioning and experience. Their brand claims help explain what they sell, but a polished store or investment headline does not establish private-company profitability or prove a specific transfer of market share. Competition supplies a reason to investigate the customer proposition; it does not supply missing financial statements.

Test a promotion with contribution after discount, fulfilment, returns and acquisition costs. Then examine whether the recruited customers return at a healthier price. Compare with a sensible baseline and allow for purchases brought forward. A temporary margin sacrifice can be a useful investment if later behaviour earns it back. If each repeat purchase requires another subsidy, the apparent growth may depend on an offer that never gets to end.

Make It Useful

Three questions for your next business conversation

  1. How much extra demand is required to recover the gross profit and contribution given away?
  2. How many discounted purchases would have happened at full price anyway?
  3. Do customers return without another subsidy, and is the remaining inventory the right assortment?
